BLOCK-PLANER FOR CLICKING-MACHINES.

To all whom it may concern:

Be it known that I, EMIL B. GOLDSMITH, a citizen of the United States, and a resident of Cincinnati, inv the county ofI-Iamilton and State of Ohio, have invented certain new and useful Improvements in Block- Planers for ClickingMachines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. V

The clicking machine as used for the stamping out of pieces of leather and like material in a wide range of industries has come to be of a definite type.

There is a block against which the cutting is done, which is a rectangular piece of wood of considerable size and thickness. There is a post adjacent the block and on the post there reciprocates the stamping arm. This arm is adapted to swing around on the post Y and upon tripping a latch it is brought down toward the block where it strikes a die as set in place by a workman, thereby cutting out a piece of leather against the block. The stamping arm is of large size dependent upon, the thickness of the die to be used. It has not been thought necessary to show or describe any furtherthan above the clicking machine to which theinvention herein may be applied. The invention relates to devices for planing off the block of such a machine, and has as its obj ect'primarily the provision of a planer which can be secured to the machine without altering or defacing the machine in any particular, and which will be extremely accurate in its work.

It is my object to provide morejparticularly for the mounting of the planer device on the stamping arm of the clicking machine, and to provide for the easy adjustment and operation of parts.

These objects I accomplish by that certain construction and arrangement of parts to be and claimed.

Specification of Letters Patent.

Patented Oct. 14, 1919.

Application filed June 5, 1917. Serial No. 172,935.

In the drawings,

F gure 1 is a top plan view of the device. F g. 2 is a side elevation thereof.

Fig. 3 is a section on the line 3, 3, of Fig, 2. j

Fig. 4 is a section on the line 4, 4, of Fig. 2.

It has not been thought necessary, as above stated, to show the parts of a clicking machine, as the only parts necessary to the operation of the planing device are the block to beplaned and the clicker stamping arm or head.

The device of my invention has a long casting 1, which has at the forward side a dovetailed track 2 for the planer. Extending rearwardly, and preferably at a slant from the dovetail are two sets of arms 3, 4, comprising each an upper and a lower arm, which said arms are spaced apart to engage snugly over the base of the stamping arm ofa clicking machine.

Extendingdown from the upper arms are the large set screws or clamping screws 5, 5, which when screwed down will press against theclicker arm and hold the dovetail track firmly in place thereon, so'as to be parallel with the plane of the base of the stamping arm, which is extremely important.

Sliding on the track is a casting having a dovetail groove 7 to fit the track. This casting forms at one side a receptacle 8. for an electric motor (not shown). Beneath this receptacle is a spider casting 9 which is held in place by set screwslO, this spider serving as a journal at 11 for the shaft of the motor, and also holds down a large fiber gear 12, which is to'be engaged by the shaft. The gear rests on. a ball bearing 13 seated in the bottom of the motor receptacle portion of the casting. i

To the side of this portion of the casting are formed the journals 14 and 15 for a sliding sleeve. 16. The lower journal is not closed but brought out in separate ears 17, 17, which are held adjustably together by a screw 18, operated by a handle 19.. By tightening the screw 18, the sleeve 16 can be clamped rigidly inplace.

- Mounted in a recess 20 inthis portion of the casting is an interiorly'threaded collar 21. The collar is knurled on the outside and is mounted over the sleeve 16 with its threads in mesh with the threads 22 formed on the sleeve 16. By operating the collar the sleeve may be raised and lowered.

Fitting down over the top of the upper journal portion of the casting is a cap. 24, which has gear teeth 25 cut thereon. The gear teeth extend through the motor receptacle portion of the casting, there being a suitable slot (not shown), and mesh with the teeth of the large fiber gear therein.

Theshaft 26 is provided, suitably keyed to the cap gear 24, and this shaft extends down through the sleeve. At its upper end beneath the cap gear, the shaft has a pair of washers 27 which bear on the sleeve on the upper end, but tightly, as the thrust on the sleeve is downwardly as will be described. At the lower ends of the sleeve is a half bearing race 28, and on the lower end of the shaft there is the other half of the bearing race at 29.

Secured to the end of the shaft is a block 30, oblong or rectangular in shape, which block may be one piece with the bearing race portion 29, if desired. The block 30 carries, set in it at an angle, the cutting knife 81, the same being held in place by means of a set screw 32.

It can be seen that to throw the block and cutter knife downwardly, the sleeve will be thrust down by means of its teeth and the collar above mentioned. The thrust from the sleeve to the block will be applied through the ball bearing 33, between the races above described. When the block has been lowered to the desired position, the lower journal should be clamped together, as described, and the block will then be held in the proper adjusted position for cutting.

It will be understood that suitable bushings for the sleeve shaft and cap gear will be provided, as shown. To retain the entire casting at a desired point on the dovetail track some such device as a screw 34 is provided, having suitable supporting brackets as at 34 and operated by a hand wheel. The screw engages the device for moving it or holding it in place, as in the follower member 3& on the motor housing.

In operating the device, after the casting has been fastened to the clicker arm, the knife holding block will be adjusted for the proper depth of cut. The operator will then start the motor and the cutter will be revolved rapidly through the medium of the gears and shaft above described. The

operator can then easily move the device across the block of the clicking machine, since the clicking machine arm is free to swing across the block, and also the device can be moved to and fro along the track since it is free to move in this direction due to. the construction above described.

The clicker arm being set properly with regard to the block, the cutter will then be set properly. The entire device can be easily slipped on and off, and nothing need be added to or removed from the clicking machine, in order to prepare it for planing, save the device now described.

The adjustment of the cutter is easy and quick, and the entire block can be planed in a short time with ordinary labor, and without any delicate adjustments, in order to get the planing machine ready to operate. The chances are that all necessary adjustments of depth and advancing the depth of cut will be done in actual practice by adjusting the stamping arm itself.

It should be noted of the device that the means shown for adjusting the planing knife and its retaining block and for rotating the knife are not the only means which may be employed within the spirit of my invention, and the knife and block adjusting means might be omitted entirely without seriously detracting from the practicability of the structure.

One of the essentials of the planer is that it is so mounted with relation to the base of the stamping arm, that the block will be planed off on the exact level of the very device which works against the block, 2'. 0., the stamping arm. Thus if the stamping arm is faulty and gets out of horizontal in a machine, the block will be planed so as to compensate for the error. The other essential is that it is a power planer for clicking machine blocks which may be mounted on the clicking machine, instead of requiring the removal of the block from the machine for planing it. The various adjustments and the feed are of value, but their broad equivalents will be sufficient to answer to the spirit of my invention in this regard.

It is not desired by the omission of mention of equivalent structures in the above description to exclude from the claims that follow the right to as broad a construction as their language permits.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
